Failure Distribution Modeling for Planned Replacement of Aircraft Auxiliary Power Unit Oil Pumps
This paper presents an application of Weibull method for forecasting the failure distribution of aircraft auxiliary power unit (APU) oil pumps for planned replacement. The Weibull method is extremely useful for maintenance planning. Using Weibull failure forecasting, a maintenance planner can make q...

| description | This paper presents an application of Weibull method for forecasting the failure distribution of aircraft auxiliary power unit (APU) oil pumps for planned replacement. The Weibull method is extremely useful for maintenance planning. Using Weibull failure forecasting, a maintenance planner can make quantitative trades between scheduled and unscheduled maintenance or nondestructive inspection and replacement. The method also helps for determining the age at which an operating part in an aircraft system should be replaced with a new part. In this study, the cumulative failure distribution of auxiliary power unit oil pumps of Boeing 737-200/300 aircraft is modeled by using simple Weibull and mixture Weibull techniques. It is demonstrated that the mixture Weibull model provides more accurate prediction for failure of the APU oil pumps. Then, the optimal replacement ages of the pumps based on the estimated Weibull parameters are calculated for various cost ratios. |
